Hello team Zeus ⚡️,

Danny here from WalletScrutiny.

We ran several tests:

  1. We used our test script together with an app-specific script for Zeus, however the build failed. We documented our efforts here.
  2. Since our current application-specific script is failing, we decided to use a custom script based off the instructions provided by Zeus here. This is currently a work in progress, but our tentative verdict for this is the results are coming off as non-verifiable.
  • We have successfully integrated a new script that's based off the instructions noted above together with our test script.
  • This is the new script:
#!/bin/bash

# Script: app.zeusln.zeus.sh
# Version: 1.1.7

# Variables passed from test.sh's metadata extraction process
appId=$appId  # Retrieved by test.sh from the APK metadata
versionName=$versionName  # Retrieved by test.sh from the APK metadata
versionCode=$versionCode  # Retrieved by test.sh from the APK metadata
signer=$(getSigner "$downloadedApk")  # Retrieved from test.sh for the official APK

# Zeus-specific variables
repo=https://github.com/ZeusLN/zeus
branch_or_tag="v$versionName"  # Dynamically use versionName from test.sh
build_dir="zeus"

# APK URLs based on architecture
declare -A apk_urls=(
    ["arm64"]="https://zeusln.com/zeus-$branch_or_tag-arm64-v8a.apk"
    ["armeabi"]="https://zeusln.com/zeus-$branch_or_tag-armeabi-v7a.apk"
    ["x86"]="https://zeusln.com/zeus-$branch_or_tag-x86.apk"
    ["x86_64"]="https://zeusln.com/zeus-$branch_or_tag-x86_64.apk"
    ["universal"]="https://zeusln.com/zeus-$branch_or_tag-universal.apk"

# Step 1: Clone the Zeus repository for the correct version
echo "Cloning the Zeus repository for version $versionName..."
git clone --depth 1 --branch $branch_or_tag $repo $build_dir

# Step 2: Change to the cloned directory
cd $build_dir

# Step 3: Run the build script
echo "Running the build script for version $versionName..."
./build.sh || { echo "Build failed"; exit 1; }

# Step 4: Find the generated APKs
apk_dir="android/app/build/outputs/apk/release/"
declare -A built_apks

I'm lead to believe we may have just had a fluke with the build we used for release (have seen this happen before). I think the path forward would be for us just to just be more judicious and run multiple build processes, before cutting it.

Thanks for reporting.

FWIW v0.9.2 will be out sooner than later so we should be able to remedy the issue in the coming weeks. Completely understand if v0.9.1 is marked as not reproducible.
